Magnetek Series 3 Drives Using “Motor 2” Option

Magnetek Series 3 Drives Using “Motor 2” Option In the summer of 2018, Engineered Lifting Systems was contracted to travel to a rather remote location in Panama to help a Magnetek user with a Hydro-Electric overhead crane. The country of Panama has many Hydro-Electric plants scattered over the country. These plants provide the majority of […]

Crane Cab Replacement Improves Function

Crane Cab Replacement Improves Function Engineered Lifting Systems was asked to review an existing application of a predominantly cab operated shipping crane. The review covered crane reliability, control method, and cab operator ergonomics. This post addresses the cab function and operator ergonomics portion of the study. The original cab as provided by the original crane […]

Runway Electrification Isolation Sections Improves Production and Provides Safety

Runway Electrification Isolation Sections Improves Production and Provides Safety It is not unusual to have multiple overhead cranes on the same runway. While maintaining and repairing these cranes, having a system that allows a partial or segmented shut down of power within a runway section for one or more cranes is a valuable option.   […]

Tapered Wheels for Top Running Cranes

Tapered Wheels for Top Running Cranes Sometimes I forget and take for granted that some knowledge in our industry is commonly known. Recently I had a chance to work with some top running cranes that had real problems with the wheels and rail.  The user complained about “racking” of the crane and was looking for […]

Custom Applications Need Gravity Safety Latches

I thought I would share two applications of the many we have been solving in the last year using our crane gravity safety latches. Keep in mind that these latches are not for every application, and a standard spring latch will do the job 99 times out of 100. These are just a couple of […]

Crane Wiring – Know What You Are Buying

When buying your next overhead crane, don’t forget to ask to what standards and what process your crane will be wired. More and more today we are seeing overhead crane manufacturers use flexible conductors for transmitting power and control voltages for extended distances on overhead cranes, gantrys, jibs, and monorails.  These flexible conductors such as […]

Variable Frequency Drives and Travel Limits

This tech bulletin is to provide insight and suggestions for applications using traditional variable frequency drives in a linear motion (Trolley or Bridge) application and have a requirement to operate that motion near mechanical stops. One look at the above picture and anyone familiar with overhead cranes will know that the trolley wheel has gouged […]
